JNK Stock Chart

Technical move. Issues from Europe could weigh in on the US banking system. If we got to the situation where there were no bids on JNK, we could see a pretty large collapse in that market. The US banking sector tracks JNK tightly as it is more of an institutional grade investment that banks do not mind holding.
